The Wiseman Threading Tools Bottom Lead Metric HSS Tap in a right-hand configuration is built for precise metric threading with dependable, repeatable results. Crafted from ground high-speed steel and delivered uncoated, this tap is designed for general-purpose use while adhering to ISO 529 dimensions, ensuring consistent fit and performance across standard applications.

• Right-hand thread, M20x1.25: a common metric specification that suits a wide range of metalworking projects.
• Bottom lead design: enables deeper thread engagement and helps achieve full-thread depth in appropriate holes.
• ISO 529 compliant: ensures compatibility with standard hole sizes and thread profiles used in fabricating and repairing metal parts.
• Uncoated HSS ground tap: delivers versatility across materials and cutting fluids, from mild steels to alloys and beyond.
• General purpose use: ideal for workshop tapping tasks, maintenance repairs, and fabrications that require reliable metric threads.

Who should consider this tap? If you’re a machinist, fabricator, or hobbyist working on metric-threaded components, this tool provides predictable performance for routine threading jobs. It’s well-suited for tapping through holes in steel, aluminum, and other machinable materials, making it a staple in a pro shop or a well-equipped home workshop.

Practical tips for optimal results: start with a clean, deburred hole; use a proper tap wrench or tapping accessory on a drill press for controlled, even advancement; apply a suitable cutting fluid to reduce friction and extend tool life; and back the tap out periodically to break chips and prevent binding. With its durable HSS composition and precise geometry, this Wiseman tap helps you achieve smooth, accurate threads that stand up to inspection and use.
